It's about bar-charts in a table.
Every row has a bar, which visualises a value of the row.
The biggest value of the whole table is the maximum of the bars and not necessarily on the same table-page. So most of the rows gonna have bars, which are shorter than the maximum.
If I fill the empty space between to the maximum, the whole impression is heavier, but if I let the space empty it will look like local "page maxima" are the full table maximum.
